+ <li> If getting unexpected <tt>"fatal error: no input files"</tt> while 
+building with MSYS make from the Windows cmd, try one of the these 
+solutions:</li>
+ <ul>
+ <li> Use MinGW <tt>mingw32-make</tt> instead of MSYS <tt>make</tt> and
+exclude the path to MSYS from PATH to prevent <tt>mingw32-make</tt> from using
+MSYS utils. MSYS utils are dependent on the MSYS runtime and they are not
+intended for being run from the Windows cmd. Specifically, makefile commands
+with backslashed quotes may be heavily corrupted when passed for execution.</li>
+ <li> Run <tt>make</tt> from the sh shell:
+<pre class="code_example">
+$ <span class="code_highlight">scan-build</span> <i>[scan-build options]</i> sh -c "make <i>[make options]</i>"
+</pre></li>
+ </ul>
+ <li> If getting <tt>"Error : *** target pattern contains no `%'"</tt> while 
+using GNU Make 3.81, try to use another version of make.</li>
